To all whom it may concern:

Be it known that I, ,FRANK J .Nroonnr, a citizen of the United States,residing at Stockdale, in the county of Pike, State of Ohio, haveinvented certain new and useful Improvements in Spring-Wheels; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in spring wheels.

The principal object of the invention is to provide a novel constructionof spring wheels adapted for use in connection with carriages, wagons,automobiles, bicycles or any other form of vehicle.

Another object of the invention is to provide a resilient wheel whichwill take up all shocks and jars incident to the passage of a vehicleover rough roads.

A further object of the invention is to provide a wheel of the characterdescribed in which any of the parts may be readily renovel combinationof parts hereinafter fully described, illustrated in the accompanyingdrawings and pointed out in the claim hereto appended; it beingunderstood that various changes in the form, proportion, size and minordetails of construction within the scope of the claim may be resorted towithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawings: Figure 1 is a side view of a resilient wheelconstructed in accordance with my invention, Fig. 2 is a transversesection therethrough, Fig. 3 is a detail sectional view of one of thecushioning means, parts thereof being shown in elevation, Fig. 4 is adetail side elevation of the hub, the covering cap being removed, Fig. 5is a perspective view of the inner section of one of the spokes, Fig. 6is a similar view of the outer section of one of the spokes, Fig. 7 is afragmentary plan view of the tire, and Fig. 8 is a detail perspectiveview of one of the sleeves.

Like reference numerals designate corresponding parts in all the figuresof the drawings.

Referring to the drawings, the wheel comprises a hub A, a rim B and aplurality of spokes C.

The hub A. includes a spaced pair of poripheral flanges 5-5, and formedin the outer face of each flange is a series of spaced marginal circularrecesses 6 which merge with the periphery of the flange, as at 7.Projecting through each flange 5 and contrally of each recess. 6 is apivot bolt 8.

The inner face 9 of the rim B is transversely. convexed throughout itsentirety, and disposed around the periphery of said rim is a tire 10which is formed with a transversely concaved tread 11 from whichprojects a series of spaced callrs 12, said calks being disposed at aninclination and having its outer surface 13 convexed.

Each spoke G includes an inner section 14 and an outer section 15. Theinner section 14: includes a body 16 and a pair of spaced legs 17--17which terminate at their ends in heads 1818, said heads being eachcentrally formed with a transverse opening 19 adapted to be engaged withthe respective pivot pins 8. The inner sections 14 normally extendradially from the hub A. The outer sections each include a body portion20 from which projects opposite pairs of legs 21 -21 and 2222respectively, the latter terminating in angular end portions 2222'"*.Each of the legs 22 is respectively pivoted at its angle by means of abolt 23 passed therethrough and through the opening 2 L formed in theouter end of the body 16 of said inner section. The outer section 15,extended, is disposed at a tangent with respect to the hub A, and hasthe free ends of the legs 21 thereof pivotally connected, as at 25, to abearing 25 which is secured to the inner face 9 of the rim B. The body20 is provided on its upper face with a rectangular metallic plate 26,and this plate and body is formed with a flared opening 27 for recelvingthe free end of a guide rod 28, the other end of said rod being threadedand engaged with a socket element 29 which is fixedly secured to theinner face 9 of'tho rim B. It will be observed in this connec tion thatthe guide'rod28 is normally dis- Q noeegeee posed at right angles to theouter section 15 of the spoke. Slidably mounted upon the rod 28 is asleeve 30 which is provided at its outer end with a flange 31. A. coilspring 32 is disposed around the rod intermediate the plate 26 and. theflange 31 above mentioned. The tension of this spring is regulated by anut 32, as will be readily understood.

Cap plates 538 533 are each disposed againstthe respective outer facesof the huh A, and are retained thereon by means of bolts 8. These platesserve not only to retain the heads 18 of the inner sections 1% againstlateral movement, but also serve to prevent dust and other foreignelements entering the recess 6 of the hub.

What is claimed is:

In a spring Wheel, the combination with a hub and rim, of a plurality ofspokes piyotaliy connected at their ends to the hub and rim andconsisting of inner and outer pivotally connected sections, the outersection of each spoke being disposed at a tan gent to the hub and formedWith a transverse opening, a guide rod disposed at right angles to theouter section and having its outer end connected to the rim, theinnerend of said rod operating in the opening of the outer section, acoil spring disposed around the rod and bearing against the outersection, and tensioning means carried by the rod and engageeble with theother end. of the spring.

In testimony whereof, I afiix my signature, in presence of twoWitnesses.
